"No one who denies the Son has the Father; whoever acknowledges the Son has the Father also." (1 John 2:23 NIV)
Long before Muhammad was born, Arabic Christians were already referring to God as Allah — and millions continue to do so today. The Allah of Islam, however, is definitely not the God of the Bible; for while Muslims passionately defend the unity of God, they patently deny His triunity. They recoil at the notion of God as Father, reject the unique deity of Jesus Christ the Son, and renounce the divine identity of the Holy Spirit.
First, while Jesus taught His disciples to pray "Our Father in heaven," devotees of Muhammad find the very notion offensive. To the
Muslims, furthermore, dogmatically denounce the Christian declaration of Christ's unique deity as the unforgivable sin of shirk. As the Qur'an puts it, "Allah forgiveth not (the sin of) joining other gods with Him; but He forgiveth whom He pleaseth other sins than this" (Sura 4:116). Muslims readily affirm the sinlessness of Christ, however, they adamantly deny His sacrifice upon the cross and subsequent resurrection. In doing so, they deny the singular historical fact that demonstrates that Jesus does not stand in a long line of peers from Abraham to Muhammad, but is God in human flesh. The Qur'anic phrase, "Allah raised him up" (Sura 4:158) is taken to mean that Jesus was supernaturally raptured rather than resurrected from the dead. In Islamic lore, God made someone look like Jesus, and this look-alike was crucified in His place. In recent years, the myth that Judas was crucified in place of Jesus has been popularized in Muslim circles due to the propagation of a late-medieval work titled The Gospel of Barnabas. Against the weight of historical evidence, the Qur'an exclaims, "they killed him not, nor crucified him, but so it was made to appear to them" (Sura 4:157).
Finally, in addition to rejecting the divinity of Jesus, Islam also renounces the divine identity of the Holy Spirit. Far from being the third person of the triune God who inspired the text of the Bible, Islam teaches that the Holy Spirit is the archangel Gabriel who dictated the Qur'an to Muhammad over a period of 23 years. This is ironic considering that Islam also identifies the Holy Spirit promised by Jesus in John 14 as Muhammad. The Bible, however, roundly rejects such corruptions and misrepresentations. The Holy Spirit is neither an angel nor a mere mortal; rather, He is the very God Who redeems us from our sins and will one day resurrect us to life eternal (e.g., Acts 5:3–4; Rom. 8:11).
